城镇污水处理厂原位扩容及提标技术应用现状

Application status of in-situ expansion and upgrading technology of urban sewage treatment plant

随着我国城镇化进程的快速推进,污水处理厂原位扩容及提标的需求日益显现。以节约占地、原位扩容及提标等需求为前提,分析现状污水处理厂原位扩容及提标工程所面临的实际问题。总结归纳近年来无预留用地的情况下,预处理工艺段、生化处理工艺段、深度处理工艺段的常见技术及应用现状。并从工艺成熟度、应用情况、扩容能力范围等方面,对生化处理段各类技术进行对比。提出污水处理厂原位扩容及提标技术决策图,对存量水厂精准施策。

With the rapid development of urbanization in our country,the demand of in-situ capacity expansion and upgrading of sewage treatment plants has become increasingly emergence.Under the requirements of land saving and in-situ capacity expansion and upgrading,this paper analyzed the actual problems faced by in-situ capacity expansion and upgrading of existing water plants.In recent years,the common technology and application status of pretreatment process,biochemical treatment process and advanced treatment process were summarized under the condition of no reserved land.Biochemical treatment technology was compared in the aspects of process maturity,application and capacity expansion.The technical decision diagram of in-situ expansion and upgrading of sewage treatment plants was proposed and implemented for existing water plants precisely.
